A little about me
Curious by nature. Backend by choice.
Early in my professional journey and serious about building things well.
01Clear APIs
02Solid data
∞Always learning
Passionate software developer specializing in backend .NET development, focused on designing and building scalable, high-performance web applications, secure RESTful APIs, and robust database architectures.
My core technical expertise centers around C#, ASP.NET Core, Entity Framework Core, and Microsoft SQL Server, where I prioritize clean code, database optimization, and maintainable system design.
Through focused training across modern software development practices—including containerization with Docker, CI/CD workflows, unit testing, and automation tools like n8n—I’m building a holistic, production-minded approach to software development.
My primary focus is backend logic and infrastructure. Foundational frontend knowledge and asynchronous programming help me connect server-side systems with the experiences they support.
Currently focused on: sharpening my backend craft, building practical projects, and learning how dependable systems are designed and delivered.

In the making
A little code, always in motion.
Animated code snippets bring a few familiar backend patterns to life—from validation and service design to reliable data workflows.
01 Start with readable, maintainable foundations.
02 Keep data, validation, and behavior intentional.
03 Improve through testing, feedback, and iteration.
